MILK-SEPARATING APPARATUS WITH SIPHON ARRANGEMENT.

the vessel on one side until the cream only.

remains in the vessel.

In the annexed drawings such a milk-separating apparatus with siphonv discharge isillustrated in one form of execution, shown by way of example only, Figure 1 being a longitudinal section and' Fig. 2 a plan.

The apparatus consists of a fiat vessel a, withoutany discharge-orifice,and into which, in order to draw off the skim-milk, a suctionsiphon 0, provided with an india-rubber bulb b, is inserted.

In order to retain the siphon c in position in the vessel a, it is provided with a footplate d, a counterpoise-weight g, which at the same time serves as a handle, and a grooved support f, which is placed over the edge of the vessel. The foot-plate d, which is attached, so that it can readily be exchanged, by means of a short piece of flexible tube a to the siphon-pipe c, is provided with several downward projections d, stamped out on the plate, and by means of which this foot-plate d rests on the bottom of the vessel, so as to permit the milk to enter the siphon-pipe freely, while nevertheless the orifice is brought as near as possible to the bottom of the vessel.

In order to use the siphon, the rubber bulb short piece of flexible tube h, attached to the discharge end of the siphon-tube, is firmly compressed with the hand, so as to close it hermetically. By the compression of the rubber bulb b the air contained in the bulb is expelled through the milk and on releasing the bulb b milk is drawn into it, and on releasing and thus reopening the flexible tube at the discharge end it the milk will run off with a continuous and fairly-rapid flow into a vessel placed under the discharge-orifice, while the cream collected at the surface of the milk is left behind in the vessel a. The flow of the milk can be stopped at any moment by compressing the bulb b.

The siphon can be cleaned bysucking water into it and reejecting it by alternately compressing and releasing the bulb.

The vessel a is provided with a cover (not shown in' the drawings) of fine wire-gauze which will not in any way prevent ventilation and the collection of cream, While, on the other hand, it will entirely prevent pollution of the milk by flies, vermin, dirt, &c., dropping into it.

Having now particularly described and ascertained the nature of mysaid invention and in what manner the same is to be performed, I declare that what I claimis 1. An apparatus for separating milk from cream which has risen from said milk, consisting of a foot-plate provided with a short tube risingfrom it, a curved siphon-tube hav- I grooved support on the lower side of said tube to engage the edge of the milk vessel, substantially as described.

2. In an apparatus for separating milk from risen cream, the combination with a curved siphon-tube of a foot-plate having a short tube rising centrally from it to engage the end of the shorter branchof said siphontube, a compressible bulb communicating with the latter, and a weight secured to said shorter branch by acurved, rigid arm, substantiallyasdescfibed?" 3. In an apparatus for separating milk from risen cream, the combination with a siphon-tube, of a foot-plate having a short tube rising from it to engage the short branch of the siphon-tube and provided with downward projections on its lower face, a compressible bulb communicating with the siphon-tube, a grooved support on the latter to engage the edge of the milk vessel, and a weight connected to said tube by a curved arm, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

EDMUND WINKLER.
